Most search queries that you will see inside Webmaster tools are for text. Sometimes you won't see it because the rankings vary quite a bit (and it's regional).

Alternatively, you can use tools like Ahrefs which will tell you all the major keywords you rank for. Google has the official data (and it's free) but Ahrefs is a close second.
After that, it's just a matter of checking manually!

I can't imagine any scenarios where you would want to check hundreds of keywords... so that might be viable.
